A wide variety of charged-particle detectors fitted with a Microdot S-93 connector can be used. Typically, one would use ORTEC ion implanted or surface-barrier detectors in a B mount; also suitable in certain applications are detectors in E or T mounts.

The sample holder trays are made of special low-background materials. The chamber is equipped with a hermetic electrical feedthrough that provides a male connection to a Microdot S-93 for ready installation of a silicon charged-particle detector and preamplifier.

A 3-inch hook-and-loop fastener is provided for connecting the preamplifier to the rear panel.

The ORTEC Model ALPHA-PPS-115 (or -230) Portable Pumping Station is an excellent choice for use with the Model 808 Vacuum Chamber. The optional vacuum hose, model 808OPT1 provides a 4-ft vacuum hose that connects to the ALPHA-PPS-115 (or -230).

CONTROLS

PUMP/HOLD/VENT

Front-panel position control for venting or pumping the vacuum chamber. A hold position independently isolates both the pump and the chamber

OUTPUTS

Detector

Rear-panel BNC connector provides connection from the detector mounted in the vacuum chamber to the preamplifier, which can be mounted to the Model 808 rear panel with a hook-and-loop fastener that is provided with the instrument.

The Portable Pumping Station, Model ALPHA-PPS-115 (or -230), consists of a cart-mounted, rotary direct-drive mechanical vacuum pump to which is attached an anti-backstreaming trap, a thermocouple vacuum gauge, and flexible bellows tubing with appropriate termination for connecting directly to the Model 808 Vacuum Chamber. The Pumping Station requires no assembly
